Abstract (en)

[origin: US2013300264A1] A control device is made more compact and an electric power steering apparatus achieving excellent ease of assembly and ease of mounting is provided by disposing the control device between a shaft of an electric motor and a gear shaft of a speed reduction structure. A control device (90) is disposed coaxially with an output shaft (11) of an electric motor (10) between the electric motor and a speed reducer, and has a heat sink (30), a power circuit board (40), a control circuit board (50), and a housing (70) in which to house the power circuit board and the control circuit board. An electronic relay circuit board (60) that passes and interrupts a motor current is housed in the housing between the power circuit board and the electric motor, so that heat generated in the electronic relay circuit board is released to the housing.
